I am having trouble understanding this question and the calculations that follow.
A beam of unpolarized light of intensity 12.2 mW/m^2 falls at normal incidence on a polarizing sheet.
a. Find the maximum value of the electric field of the transmitted beam after this first sheet.
b. Calculate the radiation pressure exerted on the polarizing sheet.
c. Now there are two more polarizing sheets placed downstream of the first sheet, each one has its transmission axis arranged at 45 degrees with respect to the previous sheet’s transmission axis. What is the intensity of the transmitted light after all three sheets?
Any help to solve this question, would be greatly appreciated! :)
A beam of light is passed through a first linear polarizing filter. A second polarizing filter is placed
after the first one. When its polarizing axis is rotated by 0 = 36 degrees with respect to the first
filter, the light intensity decreases as compared to when = 0.
What is the ratio of the light intensity after rotating the second polarizer to the intensity when 0 =
0? Give your answer in decimal form.
